Mfr.No.	CSB-RP052544h
Alternative Names	E3 SUMO-protein ligase TRIM28 (EC:6.3.2.-)KRAB-associated protein 1 ,KAP-1KRAB-interacting protein 1 ,KRIP-1Nuclear corepressor KAP-1RING finger protein 96Tripartite motif-containing protein 28, E3 SUMO-protein ligase TRIM28 (EC:6.3.2.-)KRAB-associated protein 1 ; KAP-1KRAB-interacting protein 1 ; KRIP-1Nuclear corepressor KAP-1RING finger protein 96Tripartite motif-containing protein 28
Antigen	TRIM28
Tag	N-terminal GST-tagged
Regulatory	RUO
Relevance	Nuclear corepressor for KRAB domain-containing zinc finger proteins (KRAB-ZFPs). Mediates gene silencing by recruiting CHD3, a subunit of the nucleosome rodeling and deacetylation (NuRD) complex, and SETDB1 (which specifically methylates histone H3 at 'Lys-9' (H3K9me)) to the promoter regions of KRAB target genes. Enhances transcriptional repression by coordinating the increase in H3K9me, the decrease in histone H3 'Lys-9 and 'Lys-14' acetylation (H3K9ac and H3K14ac, respectively) and the disposition of HP1 proteins to silence gene expression. Recruitment of SETDB1 induces heterochromatinization. May play a role as a coactivator for CEBPB and NR3C1 in the transcriptional activation of ORM1. Also corepressor for ERBB4. Inhibits E2F1 activity by stimulating E2F1-HDAC1 complex formation and inhibiting E2F1 acetylation. May serve as a partial backup to prevent E2F1-mediated apoptosis in the absence of RB1. Important regulator of CDKN1A/p21(CIP1). Has E3 SUMO-protein ligase activity toward itself via its PHD-type zinc finger. Also specifically sumoylates IRF7, thereby inhibiting its transactivation activity. Ubiquitinates p53/TP53 leading to its proteosomal degradation; the function is enhanced by MAGEC2 and MAGEA2, and possibly MAGEA3 and MAGEA6. Mediates the nuclear localization of KOX1, ZNF268 and ZNF300 transcription factors. In association with isoform 2 of ZFP90, is required for the transcriptional repressor activity of FOXP3 and the suppressive function of regulatory T-cells (Treg)
